[igt-dev] [PATCH i-g-t 2/5] tests/debugfs: use igt_display_require

[Daniel Vetter <daniel.vetter@ffwll.ch>]

Need to extract into a test subgroup to make sure we only skip the
tests that need display support.

v2: Chris pointed out that "read-all-entries" was the original non-kms
tests, and we don't want to skip that if there's no output. Make a
seperate test for this.

Also, that kind of where libraries magically second-guess what the
test might have wanted when it supplies an invalid request is exactly
why I want to fix the igt_display_init API regression.
